sudo python3 sound_effect . py
After the code is run, you will find that PiArm first plays the sound effect in the sound function, and then plays the
background music. When the background music is played, the [tts] function is run for timing, and the countdown
voice broadcast will be performed after 30 seconds.
Code
from robot_hat import Music,TTS
from time import sleep
m = Music()
t = TTS()
def sound ():
song = './sounds/sign.wav'
m . music_set_volume( 40 )
m . sound_play(song)
def background_music ():
music = './musics/sports-Ahjay_Stelino.mp3'
m . music_set_volume( 50 )
m . background_music(music)
def tts ():
t . say( "timing begins" )
sleep( 1 )
t . say( "three" )
sleep( 1 )
t . say( "two" )
sleep( 1 )
t . say( "one" )
sleep( 1 )
t . say( "Stop music" )
sleep( 1 )
if __name__ == "__main__" :
background_music()
sleep( 10 )
#sound()
#tts()
while True :
#background_music()
sound()
tts()
How it works?
The code is simple, it creates 3 functions
sound()
,
background()
and
tts()
, and then calls them separately to
make PiArm play music and speak.
def sound ():
song = './sounds/sign.wav'
m . music_set_volume( 40 )
m . sound_play(song)
Play the sound effect
. /sounds/sign.wav
at 40% volume.
